Hesselgren is asking for £10,000 before he will release the prototype, which will come in Linux, Mac and PC flavours. All funds go directly to the Samaritans, a UK charity supporting victims of depression.

The prototype will be given to those who donate regardless, but if the goal is met, it will be made publicly available to all.

The prototype was developed as a birthday present for Super Meat Boy co-creator Tommy Refenes and was designed as a “throw away experiment”, so it’s in pretty rough and ready form. On the Just Giving page for the project (where you can throw a few pennies in the hat should you be so inclined), Hesselgren explained a number of reasons why the prototype will never be developed as a full game – but the video below generated enough interest to inspire him to try putting it to use for charity.
